超聲沖擊處理對表層形變硬化及硬度的影響

為了探討超聲沖擊處理對沖擊表面硬度的變化，分別對Q235BT 16Mn鋼在超聲沖擊前后各種情況(原始焊態(tài)-AW、沖擊處理態(tài)-PT)焊接

接頭、表層各區域進(jìn)行了維氏硬度測試，測量結果的平均值如下表格：


                                     焊接接頭表層表面維氏硬度                                      
類(lèi)型焊縫平均硬度熱影響區平均硬度疲勞裂紋萌生區平均硬度母材平均硬度
Q235B(AW)177177187144
Q235B(PT)177224201206
16Mn(AW)206227

223

186
16Mn(RT)206253242225

從表中的相應數據可以看出：對于Q235B鋼焊接接頭，熱影響區的維氏硬度值由原始焊態(tài)的177上升到?jīng)_擊后的224，硬度提高了27%：母材的維氏硬度值由144上升到?jīng)_擊處理后的206，硬度提升了43%;對于16Mn鋼焊接接頭，熱影響區的維氏硬度值由原始焊態(tài)的227上升到?jīng)_擊處理后的253，硬度提高了11%;而母材的維氏硬度值186上升到?jīng)_擊處理后225，硬度提高了21%。
