钢板温态拉伸性能和拉深 性能与温度的关系 ——钢板温态成形性(Ⅰ) 详细地分析不同钢板温度在600℃的范围内进行单拉伸和圆柱形深拉深时温度对成形性能的作用。对于不同的材料,例如,加钛的超低碳钢,由于不出现“兰脆”现象,当提高温度时抗拉强度(TS)呈单调减小。然而,对于正常的普通碳钢,“兰脆”现象发生在200℃～300℃的范围。此时抗拉强度提高是由于“兰脆”时(C+N)溶解物的大量增加的缘故。当抗拉强度与温度的
RELATIONSHIP BETWEEN TEMPERATURE TENSILE BEHAVIOR AND DRAWING BEHAVIOR OF STEEL PLATE AND TEMPERATURE - TEMPERATURE FORMING BEHAVIOR OF STEEL PLATE (Ⅰ) The effects of temperature on the profile during single stretch and deep cylindrical drawing at 600 ℃ are analyzed in detail. The role of performance. For different materials, for example, ultra-low carbon steels with titanium, the tensile strength (TS) decreases monotonically as the temperature is raised because “blue brittleness” does not occur. However, for normal plain carbon steel, “blue brittle” phenomenon occurs in the range of 200 ° C to 300 ° C. The increase in tensile strength at this time is due to the large increase in (C + N) dissolved matter in “blue crisp”. When the tensile strength and temperature
