The observation and the data were then used to setup the stress - strain - temperature relation for formability study of SS400 steel plates. The same method can be used to establish the mechanical properties at elevated temperatures.Vuong Gia Hai...
aSS400热轧带钢存在力学性能不合格现象,对力学性能不合格的SS400试样进行化学成分、夹杂物、金相组织分析。结果表明:SS400热轧带钢抗拉强度Rm偏低的主要原因有两个,一是Mn含量偏低;二是厚度较大的热轧带钢轧后冷却时,层流冷却能力不足,卷取温度偏高,导致晶粒粗大,最终造成热轧带钢强度不合格。断后伸长率不合格的原因是...
The effect of heat treatment on the electrochemical and mechanical properties of SS400 steel was investigated, and the effects of annealing conditions on notched specimens subjected to the slow strain rate test (SSRT) were studied. The results show that no correlations are observed among the maximu...

The gastric mill of Decapoda is a unique feature, which comprises teeth, stabilizing ossicles, and particle sorting setae. Involved in the fragmentation and sorting of the food, this structure serves as interface between the organism and its environment. As material properties complement morphology an...
The fates and functions of bone cells are determined by the physical and chemical properties of their niches. The niche is a three-dimensional structure consisting of extracellular matrix (ECM) components together with the cells they surround and connect.28 The ECM itself is composed of collagens...
