“…Mechanical properties of pearlitic steels are known to depend strongly on the interlamellar spacing of pearlite. [16][17][18] Various heat treatment processes have been applied to obtain desirable pearlite interlamellar spacing and mechanical strength of steels. In this research, an attempt was made to obtain the quantitative correlations among microstructure, strength and magnetic properties of variously heat treated eutectoid steel.…”

Microstructures and strength of variously heat treated eutectoid steel were evaluated by magnetic property measurements. Isothermal transformation, continuous cooling or spheroidization heat treatment was performed to produce various microstructures. Microstructural parameters (phase, pearlite interlamellar spacing), mechanical properties (fracture strength) and magnetic parameters (coercivity, remanence, hysteresis loss, saturation magnetization) were measured to investigate the relationships among these parameters. Coercivity and remanence were observed to be high in order of martensite, pearlite and ferrite phase. The linear decrease of coercivity and remanence with the interlamellar spacing and the linear increase of those with fracture strength of pearlitic eutectoid steel were found. Coercivity and remanence were suggested as potential magnetic parameters for discriminating phases and quantitatively assessing the pearlite interlamellar spacing as well as strength of eutectoid steel.

“…Some researchers [2][3][4][5][6][7][8][9][10][11][12][13][14] have discussed erosion mechanisms for some metallic materials. They utilized mechanics analysis to get results, which are summarized as follows: cutting erosion occurs at a low incident angle and deformation erosion occurs at a high incident angle.…”

Erosion Behavior of CA-15 Tempered Martensitic Stainless Steel

Martensite stainless steel (MSS) possesses excellent strength and medium corrosion resistance, and is often used in industrial applications, such as for highly stressed parts like turbine blades and pipe materials. However parts are often damaged by flow field particles interact with the materials, in a solid particle erosion (SPE) phenomenon, which may even lead to injuries. In this paper we discuss the effects of the tempering treatment and the erosion incident angle on the CA-15 MSS erosion behavior. The results show that, in single particle erosion tests, the main mechanisms that cause problems are micro-cutting and deformation craters at low and high incident angles, respectively. In repetitive particle erosion tests, grain boundary cracking is one of the main fracture mechanisms. The platelet mechanism also obvious affected at high incident angle erosion. Materials tempered at 573-673 K, tempered martensitic embrittlement (TME) occurred, which caused serious boundary cracking and grain broken-down. The serious erosion damage showed at medium incident angle for this material that result in combine of cutting, deformation crater, and cracking mechanism. The maximum erosion rate of material occurred at an incident angle of =6 and the deepest erosion penetration occurred at an incident angle of =4.

“…The results showed that the peak angle of the erosion rate curve did not shift or vary with the volume fraction of pearlite. However, other studies [11][12][13] revealed that when the full ferrite matrix is transformed into pearlite, the peak angle of the erosion rate curve shifts to a higher angle. The above results indicated that the change in the peak erosion rate due to changes in the lamellae cementite needed to be explored for PDI.…”
