Various thermo-mechanical treatments were applied to refine and homogenise grain size and improve mechanical properties of hot-isostatically pressed (HIP) 14%Cr ODS ferritic steel. The grain size was reduced, improving mechanical properties, tensile strength and Charpy impact, however bimodal-like ...
13.An investigation was made on the effect of rewelding on mechanical properties of Ultra-low carbon austenitic stainless steel based on mechanical properties test andmicrostructureexamination. 通过对反复焊接1～5次的超低碳奥氏体不锈钢力学性能的试验及金相组织的分析,研究了反复焊接对超低碳奥氏体不锈钢力学...
Examination of microstructure revealed smaller size of block and larger number of high-angle grain boundaries with higher Mn content. The change of the ultimate tensile strength and toughness with increasing Mn content was attributed to the increased hardenability, the number of high-angle grain ...
Tests have been performed to examine the yield stress and the cleavage fracture stress at 196°C of SA 508 Class 2 pressure vessel steel in a range of heat treatment conditions. The heat treatments either varied the austenitization temperature before isothermal transformation at 450°C or varied...

摘要:Examination of selectively etched tool steel microstructures by light microscopy provides more information than standard etchants, such as nital, picral or Vilella's reagent. Further, the images are more suitable for quantitative measurements, especially by image analysis. Specimens must be properly...
After we have properly prepared our tool steel specimens, it is generally best to examine them as-polished before etching – unless we are simply doing a routine test, for depth of decarburization, degree of spheroidization, and so forth. Examination of selectively etched tool steel microstru...
examination to the fracture surface of specimens with scanning electronic microscope.The results show that fracture morphology of the low carbon Si-Mn QP steel is a dimple pattern with features of plastic fracture.The retained austennite play a role of phase transformation induced by plastic ...
By intermittent examination of samples for telltale opalescence at various times and temperatures, it is possible to construct a time-temperature-transformation diagram. The microstructure developed in this process depends on the curvature of the free-energy vs. concentration curve. The loci of ...
