“…The distribution of Ta is similar to that of W, with higher content in bright cores and lower in grey rims. However, partial V/Zr/Nb elements are also found in the binder, which is agreed with Liu's results …”

“…1,5,14 Manoj Kumar 18 have revealed that the TaC in cermets refined the microstructure and attributed to reduced wear during the dry machining. Liu 19 has found that NbC lowered the sintering temperature, with limited solubility in thee rims. Kang's work 20 shows that Ti(C,N)-based cermets containing 5 wt% ZrC exhibit impressive oxidation resistance at 750°C for 100 hours, with a low weight gain of 2.8 × 10 −6 g·mm −2 .…”

Core‐rim structure, concerning its interface structure and internal stress, plays an important role in mechanical performance of Ti(C,N)‐based cermets. Four types of cermets containing equimolar TaC, VC, ZrC, and NbC were fabricated, in order to reveal the synergetic relationship between core‐rim structure and mechanical properties. VC and ZrC effectively inhibited the grain growth, while TaC and NbC favored for coarser core‐rim grains. A thin distortion layer at the rim‐binder interface was confirmed, formed during the solidifying stage. Compared to the TaC, ZrC and NbC, VC shrunk the lattice parameters of rims and effectively decreased the lattice misfit of the distortion zone from around 4.0%‐0.8%. Cermets containing VC showed satisfactory bending strength of 2099 MPa and toughness of 10. 3 MPa m1/2, owing to the strengthened rim‐binder interface. TaC and NbC exhibited the similar roles in cermets with comparable mechanical properties, while addition of ZrC increased the lattice misfit of core‐rim structure, resulting in poor mechanical performance. Decreased lattice misfit of rim‐binder interface changed the fracture mode of cermets from intergranular to transgranular fracture, with in‐situ formed dimples.

“…There has been increasing interest in composites and many researchers contributing their work in the area of wear analysis of aluminium composites, cermets, ceramics [30][31][32][33][34][35][36][37][38][39][40]. Umanath et al [30], examined the effect of SiC and Al 2 O 3 on dry sliding wear behaviour of Al6061 hybrid composites prepared by stir casting method, results showed that with increase in the volume content, wear decreases due to the presence of hard oxide particles.…”

Advanced mechanical and wear properties and applications of composites with bases of light weight metals have led to the need of aluminium (Al) metal matrix composites (MMCs). In today's time aluminium (Al) metal matrix composites (MMCs) are considered the most potential material for structural and functional applications. Composite materials with aluminium matrices are used in defence, aerospace, automotive and aviation, thermal management areas. Beneficial properties with reduced prices have enlarged their applications. To obtain desired physical and mechanical properties like high hardness, high strength, high stiffness, high wear, abrasion and corrosion resistance Al is reinforced with different metallic, non-metallic and ceramic elements. Al MMCs are used to make piston, connecting rod, engine cylinders, disc and drum brakes where wear has a great role in the functioning of these components as excessive wear of the mating components sometimes leads to catastrophic failures. Improvement of mechanical, especially tribological properties of hybrid composites were provided by the use of certain reinforce materials such as SiC, Al 2 O 3 and graphite. Hence the present chapter presents a review on aluminium metal matrix composites (MMCs) reinforced with different particulate, whisker, fibres reinforcements highlighting their effect on physical, mechanical and wear behaviour of Al MMCs.

“…Stereology has been used to characterize a three-dimensional (3D) microstructure in terms, for example, of the abovedescribed parameters for several years now, while only analyzing two-dimensional (2D) micrographs ( Ref 10). The principle, however, remains the same nowadays, even with more powerful microscopes and computers available: The linear intercept (LI) method is still widely used to characterize microstructures (Ref [11][12][13][14][15][16]. This method consists in drawing test lines over a micrograph and counting the amount of intercepts of the carbide-carbide and carbide-matrix interfaces as well as measuring the length of each newly defined segment throughout each line ( Ref 17).…”

The present work describes a new methodology designed to characterize the microstructures of tool steels containing carbide hard phases, with the focus set on their abrasive wear resistance. A series of algorithms were designed and implemented in MATLABÒ to (i) recognize each of the features of interest, (ii) measure relevant quantities and (iii) characterize each of the phases and the alloy in function of attributes usually neglected in wear description applications: size distribution, shape and contiguity of the hard phases. The new framework incorporates new parameters to describe each one of these attributes, as observed in SEM micrographs. All three aforementioned stages contain novel contributions that can be potentially beneficial to the field of materials design in general and to the field of alloy design for severely abrasive environments in particular. Models of known geometry and micrographs of different powder metallurgy steels were analyzed, and the obtained results were compared with the obtained by the linear intercept method. The relation between the new parameters and the ones available in the scientific literature is also discussed.
