前言为给实际生产提供依据,可在实验室采用热加工试验方法确定金属和合金的热加工性能。这样即可以用简单、经济的办法保证在实际生产中得到优质产品。热加工性能的试验方法有多种形式,如热扭转、热拉伸、热压缩、热冲击拉伸、冲击顶锻以及热弯曲等。这些试验方法各有其 Preface To provide the basis for actual production, thermal processing test methods can be used in the laboratory to determine the hot working properties of metals and alloys. In this way, you can use simple, economical methods to ensure that in the actual production of quality products. Test methods for hot workability are available in a variety of forms, such as hot torsion, hot drawing, hot drawing, thermal drawing, impact topping, and hot bending. These test methods have their own
