“…Ion implantation causes changes in the physical, chemical, and mechanical properties of the surface layer of metals. By purposefully choosing the alloying element and ion irradiation modes, it is possible to provide a wide range of useful properties of the surface layers of materials, namely, to increase the strength and yield strength, impact strength, crack, corrosion, and wear resistance of metals and alloys [1][2][3][4][5].…”

Commercial rolled AISI 321 stainless steel samples were irradiated with Al+ ions with an energy of 80 keV and fluence of 1017 ion/cm2. The effect of Al implantation on the chemical and phase composition of the steel surface layer was studied by X-ray electron spectroscopy and grazing beam mode of X-ray diffraction analysis. A thin surface layer down to a depth of 30 nm after Al+ ions implantation consists mainly of metal oxides. In the near-surface layers of 5 nm in depth, a noticeable depletion in chromium and nickel was observed. A surface layer (up to 0.5 µm) of non-irradiated steel, in addition to the f.c.c. austenite γ-phase, consists of up to 20 vol% of the b.c.c. α′-phase, which formed at rolling as a result of mechanical deformation. Al implantation results in the significant increase in the α′-phase amount in the surface layer at a depth up to 2 µm. It is indicated that the observed γ → α′ transformation at ion irradiation proceeds predominantly as a result of the effect of post-cascade shock waves, but not as a result of the surface layer chemical composition changes.

“…There is a large existing body of work on the tribological and wear properties of AISI 420 stainless steel [8,9,10,11,12,13,14,15,16,17]. Recently, D’Ans et al [8] studied the tribological and wear behaviors of the AISI 420/Fe 2 B surface layer by ball-disc tribological and wear tests.…”

“…The results indicated that low-temperature plasma carburization can effectively reduce wear; the wear mechanism for the specimen treated at 500 °C was slight oxidative wear. In addition, laser surface cladding [12], surface nitriding [13,14,15], diamond-like surface coatings, [16,17] and other techniques have been used to examine the tribological and wear properties of AISI 420 steel under different conditions. However, there have been only a few reports to date, on the effects of proton irradiation on the tribological and wear properties of steel.…”

In this paper, low-energy proton irradiation experiments with different cumulative fluences were performed on samples of AISI 420 stainless steel that were either annealed or tempered at 600 or 700 °C. The effects of the cumulative proton irradiation fluence on the evolution of the microstructure of AISI 420 were studied by transmission electron microscopy (TEM). Scratch tests were performed using a Tribo Indenter nanomechanical tester, in order to investigate the effects of the cumulative fluence on the tribological properties of the AISI 420 stainless steel. The results indicate that the dislocation density of the microstructure near the surface of the AISI 420 stainless steel increases with higher cumulative proton irradiation fluences. Under the same load, the nanoscale friction coefficient and wear rate both decreased with increasing cumulative proton irradiation fluence. This indicates that the surface hardening effect induced by proton irradiation can diminish the nanoscale friction coefficient and wear rate.

“…The effect of austenitizing on the microstructure and hardness of two martensitic stainless steels was examined to ensure a martensitic structure with minimal retained austenite [5]. Another experiment performed was implantation of nitrogen ions at various energies and doses into the surface of AISI 420 martensitic stainless steel [6]. The main problem related with the welding of low carbon 12% Cr stainless steels is its hydrogen induced cracking susceptibility.…”

Theoretically, the preheating temperature refers to the start martensite temperature (Ms), and the martensite transformation can be considered as the conservation of the invariant habit-plane in the lattice structure. The habit-plane is the interface plane between austenite and martensite as measured on a macroscopic scale. From the calculation, Ms = 252 °C. The martensite formation can be affected by temperature or stress treatment. In this experiment, temperature treatment was conducted. The sample was treated at 250 °C ± 10 °C. Before and after the pre-heat treatment, the sample was characterized using the neutron diffraction method. BATAN's Texture Diffractometer (DN2) with a neutron wavelength of 1.2799Å was used to characterize the sample. Analysis of the crystal structure showed that there are three phases before the preheating. The lattice parameters (a) obtained were as follows: for the -phase, a = 2.8501 ± 0.0004 Å; for the α'phase, a= b =2.517 ± 0.003 Å, and c= 3.581 ± 0.002 Å; for the -phase, a= 3.5884 ± 0.0004 Å, Rwp = 17.94%, and  = 1.33. After preheating, only the -phase appears with a = 3.5830 ± 0.0005 Å, Rwp = 26.03%, and  = 1.17. The orientation distribution function is modeled by the sample symmetrization model based on triclinic to orthorhombic sample symmetry. It shows that, before being preheated, the -phase has {100} <001> with texture index (F 2 ) between 0.701 m.r.d. to 3.650 m.r.d., the α-phase has a texture index between 0.923 m.r.d. to 1.768 m.r.d., and the '-phase has a texture index between 0.910 m.r.d. to 1.949 m.r.d. After being preheated, the -phase also has {100} <001> with a texture index between 0.846 m.r.d. to 3.706 m.r.d. It can be concluded, that because of the high preheating temperature, a phase change from martensite to austenite occurred that allowed the sample to be welded easily. After preheating, the -phase has the same cubic type orientation {100} <001>, and the texture index is nearly the same as that before preheating, with not martensite present. AbstrakPengaruh Suhu Pemanasan-Awal pada Struktur Kristal dan Tekstur Baja Tahan Karat Martensitik. Secara teoritis, suhu pemanasan awal mengacu pada suhu martensit awal (Ms), dan transformasi martensit dapat dianggap sebagai konservasi dari habit-plane invarian dalam struktur kisi. Habit-plane adalah bidang antarmuka antara austenit dan martensit yang diukur pada skala makroskopik. Dari perhitungan, Ms = 252 °C. Pembentukan martensit dapat dipengaruhi oleh suhu atau perlakuan tekanan. Dalam percobaan ini, perlakuan suhu dilakukan. Sampel diperlakukan pada 250 °C ± 10 °C. Sebelum dan sesudah perlakuan pemanasan-awal, sampel dikarakterisasi menggunakan metode difraksi neutron. Difraktometer Tekstur BATAN (DN2) dengan panjang gelombang neutron 1,2799 Å digunakan untuk mengkarakterisasi sampel. Analisis struktur kristal menunjukkan bahwa ada tiga fase sebelum pemanasan awal. Parameter kisi (a) yang diperoleh adalah sebagai berikut: untuk fasa-α, a = 2,8501 ± 0,0004 Å; untuk fasa-α', a = b = 2,517 ± 0,003 Å, dan c = ...
