style="text-indent:25px">冷拔加工使材料除了有拉伸變形外還有擠壓變形冷拔加工一般要在專門的冷拔機(jī)上進(jìn)行。鋼材經(jīng)冷加工后，產(chǎn)生一定的塑性變形，屈服點明顯提高，即強(qiáng)度和硬度明顯提高，但塑性和韌性有所降低，這種現(xiàn)象稱為鋼材的冷加工強(qiáng)化（或冷作強(qiáng)化）。通常冷加工變形越大，則強(qiáng)化越明顯，即屈服強(qiáng)度提高越多，而塑性與韌性降低也越大。圓鋼在冷拔過程中，不僅受拉，同時還受到擠壓作用。經(jīng)過一次或多次冷拔后，圓鋼的屈服強(qiáng)度可提高40%～60%，但塑性**降低，具有硬鋼的性質(zhì)。</p><div
