heat diffusion zone

基本解釋

The diffusion zone width of main alloying elements increases and hardness of the friction weld zone near TC4 titanium alloy side improves after post-weld heat treatment.
經(jīng)焊后回火熱處理后，主要合金元素沿焊合區(qū)的擴(kuò)散區(qū)寬度增大；焊合區(qū)鈦合金側(cè)硬度值顯著提高。
The bonding and diffusion characteristics at the interface of welding layer and substrate, and the heat-affected zone were analysed as well. It was proved that the micro-area pulse spot welding is an…
分析了焊補(bǔ)層與基體間的結(jié)合特點(diǎn)、擴(kuò)散情況及熱影響區(qū)，證明微區(qū)脈沖點(diǎn)焊是一種操作簡(jiǎn)便、性能可靠的模具修補(bǔ)新技術(shù)。
