在机器制造厂里,我們常常希望把机器做得又灵巧,又結实。好机器都得用性能优良的鋼材。怎样来改善鋼材的性能呢?除了进行适当的热处理外,最好的方法,是加入一些合金元素,像鎳、铬、鎢、钼、釩等等。加入了合金元素的鋼就叫做合金結構鋼。合金結構鋼和碳結構鋼不同的地方主要是成分。前次我們講过,决定碳結構鋼性能的主要元素是碳,而决定合金結構鋼性能的元素除了碳以外,还
In machine builders, we often want to make the machine smart, solid. Good machines have to use good performance of steel. How to improve the performance of steel? In addition to the appropriate heat treatment, the best way is to add some of the alloy elements, such as nickel, chromium, tungsten, molybdenum, vanadium and so on. Join the alloying elements of steel called alloy steel. Alloy structural steel and carbon structural steel is mainly composed of different parts. The last time we talked about, the main element that determines the performance of carbon structural steel is carbon, and the elements that determine the performance of alloy structural steel, in addition to carbon
