α單相黃銅管（從H96至H65）具有杰出的塑性，能承受冷熱加工，但α單相黃銅管在鑄造等熱加工時(shí)易呈現(xiàn)中溫脆性，其具體溫度范圍隨含Zn量不一樣而有所改變，通常在200～700℃之間。因而，熱加工時(shí)溫度應(yīng)高于700℃。單相α黃銅中溫脆性區(qū)發(fā)生的原因主要是在Cu-Zn合金系α相區(qū)內(nèi)存在著Cu3Zn和Cu9Zn兩個(gè)有序化合物，在中低溫加熱時(shí)發(fā)作有序改變，使合金變脆；別的，合金中存在微量的鉛、鉍有害雜質(zhì)與銅構(gòu)成低熔點(diǎn)共晶薄膜散布在晶界上，熱加工時(shí)發(fā)生晶間決裂。實(shí)習(xí)標(biāo)明，參加微量的鈰能夠有效地消除中溫脆性。 </p> <p> 兩相黃銅管（從H63至H59），合金安排中除了具有塑性杰出的α相外，還呈現(xiàn)了由電子化合物CuZn為基的β固溶體。β相在高溫下具有很高的塑性，而低溫下的β′相（有序固溶體）性質(zhì)硬脆。故（α+β）黃銅應(yīng)在熱態(tài)下進(jìn)行鑄造。含鋅量大于46%～50%的β黃銅因功能硬脆，不能進(jìn)行壓力加工。徐州節(jié)能毛細(xì)紫銅管質(zhì)量保證</p><p
