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...
Fig. 11. Variation in mechanical properties of the experimental steel with aging temperature: (a) yield strength, (b) −80 °C Charpy impact energy. 4. Discussion 4.1. Effect of nanoprecipitates on mechanical properties The variation of strength during aging process is influenced by two competit...
For the same reason, optimizing a primary sequence for two properties at the same time will be more difficult especially when most motifs have contrasting effects on the two properties. For instance, it may be desirable to increase both ϵf and σUTS, however, motifs like SS have negative ...
3. Good mechanical properties Excellent performances hot-rolled steel products1. High strength, good toughness, 2. Easy for molding process and good weldability, Main application1. Automobile, Bridges, Buildings, 2. Machinery, Pressure vessel industries. ...
The mechanical properties relate to the diameter of the wire. As a rule of thumb Rm=2220 - 820 log d, according EN 10270-1-SH for steel nr. 1.1200. For stainless steel 1.4310 the tensile strength is 15% less, according EN 10270-3-NS. The max bending stress is taken 0.7Rm, the max...
A comparative investigation of mechanical properties of Ti-6Al-4V titanium alloy with microcrystalline and submicrocrystalline structures in the temperature range of 20-600°C has been carried out. The grain sizes under the submicrocrystalline and microcrystalline conditions are 0.4 and 10 μm, respecti...
We have demonstrated that protein function is retained in stiff low-molecular-weight gels when stored at temperatures as high as 50 °C for up to 4 weeks by preventing irreversible aggregation. Owing to the unique mechanical properties of the low-molecular-weight gels, they break when passed...
making and doctor-blading19, have been intensively studied and are demonstrated to be environmental friendly, energy-efficient, economic, very efficient, and versatile for fabricating large-area, two-dimensional (2D) nacre-mimetic films with impressive nacre-like structures and mechanical properties20, ...
