一步發(fā)展，是一種典型的材料-工藝一體化技術(shù)，黃銅粉粉末冶金材料。其工藝過(guò)程為:首先根據(jù)產(chǎn)品外形計(jì)算設(shè)計(jì)出產(chǎn)品的模具（包套），隨后充填金屬粉末，再經(jīng)真空抽氣后進(jìn)行熱等靜壓得到全致密的金屬零部件，采用少量機(jī)加工或化學(xué)腐蝕的方法去除包套可獲得力學(xué)性能與鍛件相當(dāng)、尺寸精度可達(dá)0.2

所制備構(gòu)件在成形過(guò)程中承受各向同性氣壓作用在各個(gè)方向受力均勻，因而成形后的性能也是各向同性且均勻的； </p> <p> (3)、結(jié)構(gòu)適應(yīng)性好 </p> <p> 成形用芯?？刹捎梅煮w式設(shè)計(jì)，黃銅粉粉末冶金材料，能夠滿足各類不同形狀產(chǎn)品的需求具有較高的柔性； </p> <p> (4)、成本較低 </p> <p> 該工藝具有較高的材料利用率和成品率，能夠在提高效率的同時(shí)明顯降低了生產(chǎn)成本。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="黃銅粉粉末冶金材料"

在粉末冶金材料的熱處理中，為了提高淬透性，通常加入一些合金元素如：鎳、鉬、錳、鉻、釩等，它們的作用跟在致密材料中的作用機(jī)理相同，可明顯細(xì)化晶粒，當(dāng)其溶于奧氏體后會(huì)增加過(guò)冷奧氏體的穩(wěn)定性，保證淬火時(shí)的奧氏體轉(zhuǎn)變，使淬火后材料的表面硬度增加，淬硬深度也增加。另外，粉末冶金材料淬火后都要進(jìn)行回火處理，回火處理的溫度控制對(duì)粉末冶金材料的的性能影響較大，因此要根據(jù)不同材料的特性確定回火溫度，降低回火脆性的影響，一般的材料可在175-250℃下空氣或油中回火0.5-1.0h。 </p> <p> 2、化學(xué)熱處理工藝 </p> <p> 化學(xué)熱處理一般都包括分解、吸收、擴(kuò)散三個(gè)基本過(guò)程，比如，滲碳熱處理的反應(yīng)如下： </p> <p> 2CO≒[C]+CO2 (放熱反應(yīng)) </p> <p> CH4≒[C]+2H2 (吸熱反應(yīng)) </p><div
