[請益] 關於期刊英文翻譯...

[xe7961 (xe7961)]

小弟最近讀到某篇製造相關的期刊,但讀到某一段真的是看不懂文意...

煩請版上強者為小弟解惑

內文如下:
In the weld metal with lower strength, as in the case

of GTAW joint, since the deformation and the yielding

are mainly concentrated in the weld metal zone, the

extension of the plastic zone is limited within the weld

metal. As soon as the plastic zone reaches the fusion line,

plasticity keeps on developing along the interface

between the parent material and the weld metal[19]. The

triaxial state of stress is high in the weld metal and the

relaxation of this stress is poor. The crack driving force

needed for crack extension is small, so the fracture

toughness of the weld metal with lower strength is not

high. On the other hand, if the strength of the weld metal

is more or less equal to the base metal, as in the case of

FSW joint, the plastic zone can easily extend into the

parent material because the deformation and yielding

occur in both weld metal and the base metal. The stress

relaxation can easily take place in the crack tip region, so

more crack driving force is needed for crack extension

and the fracture resistance of the weld metal with higher

strength is greater than that of the lower strength[20].

This is also one of the reasons for the better fatigue

performance of the FSW joint.

→ xe7961:一些專有名詞都不知道要怎麼翻~"~
推 michaelgodtw:太長我也懶得看,專有名詞不要翻就好了
推 alpha008:哪些專業名詞看不懂？ 還是整篇都看不懂...?
推 alpha008:大致上是說 惰氣鎢棒電弧銲因變形與降伏大都集中於銲料
→ alpha008:區，所以塑變區也被侷限與此區域。此區域之高應力也造成
→ alpha008:銲材有較低的破壞韌性與較小的裂縫成長驅動力。相較於摩
→ alpha008:擦攪拌則是相反，因此fsw joint相對較優....後面比對一下
→ alpha008:前面看應該看得懂 懶得打 名詞都差不多
→ alpha008:補充一下 fsw joint 不應該說是相反 是它的銲料跟母材因
→ alpha008:為根本就是同材料 所以強度、性質幾乎是差不多  不是指銲
→ alpha008:料強度高過母材喔
