delayed fracture properties of 1500MPa bainitemartensite dual-phase high strength steels and hydrogen traps in them have been investigated. 2. Experimental Procedure The materials investigated were vacuum-induction melt-ing bainitic steels (U20Si, XBU25A, U25A, U20DSi), and 30CrMnSiA high strength steel was selected to compare Effect of Microvoid Formation on the Tensile Properties of The major difference between tured tensile specimens showed that microvoids were formed Fig. 1 Dependence of martensite volume fraction on annealing temperature Fig. 2 Effect of martensite percentage on UTS and elongation (%) Table 2 Heat treatment and mechanical properties of 30CrMnSiA low alloy steel Heat treatment Martensite Yield stress UTS
30CrMnSiA has high strength and sufficient toughness after quenching and tempering, and hardenability is also good. After quenching and tempering, the material can be used as a grinding wheel shaft, gears and sprockets. 30CrMnSiA has good processability, small National Standard of PRC Alloy Structure Steels GB/T Foreword The standard has revised GB/T 3077-1988 The Technical Conditions of Alloy Structure Steel. There have been some changes in this nationals standard over its previous edition in the following
Full length article SLM-manufactured 30CrMnSiA alloy:Mechanical properties and microstructural effects of designed heat treatment Lin-zhi Wanga,1, Jiao-jiao Wua,,1, Xue-fei Huangb, Xing-fu Hongc a Chongqing Key Laboratory of Additive Manufacturing Technology and Systems, Chongqing Institute of Green and Intelligent Technology, Chinese Academy of Sciences, Progressive damage characteristics of screwed single-lap From the analysis and discussion mentioned previously, it is argued that the PDM proposed in this work is a rational and valid basis for predicting mechanical characteristic and failure mechanism of screwed single-lap CCF300/AC721-30CrMnSiA joint, only with the input of basic properties of materials and joint geometry and dimensions.
As a result, tempered sorbite as an equilibrium microstructure in ambient environment was obtained in SLMed 30CrMnSiA alloy parts. The optimum comprehensive mechanical properties of SLMed parts with an average hardness of 24.8 HRC, a tensile strength of 860 MPa, a plasticity of 16.9% and an impact toughness of 29.1 J were achieved by performing the designed heat treatment mode.
