由于在包装和建筑工业中,对较高强度材料的需要增加,迫使制造者去探索生产另一种具有较高强度水平材料的可能性。从不同的材料中选择作为指定用途的材料时,材料的成本是最重要的考虑因素之一,通常,是选择既能满足技术要求,又是最经济的材料。过去,为了改善机械性能作了各种各样的试尝,它们可以归纳为下面的三类:用各种元素作为合金化的基本成分;用不同种类的热处理生产出不
As the need for higher strength materials has increased in the packaging and construction industries, manufacturers have been forced to explore the possibility of producing another material with a higher strength level. The cost of materials is one of the most important considerations when choosing materials from a range of materials for their intended use. Often, the choice is made of materials that meet both the technical requirements and the most economical use. In the past, various attempts have been made to improve the mechanical properties. They can be grouped into the following three categories: using various elements as the alloying elements; using different types of heat treatment to produce
