機械工程材料

內(nèi)容概要

《機械工程材料(雙語版)》主要包括兩部分：第一部分是基礎(chǔ)部分，包括材料的性能、結(jié)構(gòu)與組織，相圖與相變，使學生一般性地建立材料的成分、組織、性能及工藝間的聯(lián)系；第二部分是應用部分，介紹常用材料的成分、組織、性能及工藝間聯(lián)系，也是對第一部分知識的鞏固。每一章節(jié)前面以通俗的例子開始，逐漸引人專業(yè)概念，每章最后有供學生討論的問題，以使學生迅速建立材料的科學基礎(chǔ)，同時將所學知識盡可能與實際和應用相結(jié)合，提高分析問題和解決問題的能力。全書由齊民統(tǒng)稿并最后定稿。

章節(jié)摘錄

　　Forming operations are those that the shape of a metal piece is changed by plasticdeformation; for example,forging,rolling,extrusion,and drawing are common formingtechniques. Of course,the deformation must be induced by an external force or stress,the magnitude of which must exceed the yield strength of the material. Most metallicmaterials are especially amenable to these procedures,being at least moderately ductileand capable of some permanent deformation without cracking or fracturing.　　When deformation is achieved at a temperature above which recrystallization oc-curs,the process is termed hot working（Section 7. 12）, otherwise,it is cold working.With most of the forming techniques,both hot-and cold-working procedures are possi-ble. For hot-working operations,large deformations are possible,which may be succes-sively repeated,because the metal remains soft and ductile. Also,deformation energy re-quirements are less than that for cold working, However,most metals experience somesurface oxidation, which results in material loss and a poor final surface finish. Cold　　working produces an increase m strength with the attendant decrease in ductility,sincethe metal strain hardens; advantages over hot working include a higher quality surfacefinish,better mechanical properties,and closer dimensional control of the finished piece.On occasion,the total deformation is accomplished in a series of steps in which the pieceis successively cold worked a small amount and then process annealed However,this isan expensive and inconvenient procedure.　　……
