Koom nyob rau hawj tswv teb chaw yog hais tias lub tsis ntawm kev cai li cas? Kev cai li cas:

1. Txhob ntsuam metallurgy yooj rau hais tias cov xovxwm ua kev caij lwm thiab txoj, yog li cas teb chaw ntawm qhov kawg lub, tsis muaj rau hais tias qhov kawg lub yog cov qhov gear. Nrog txhob ntsuam metallurgy, li cas teb chaw ua hauv lawv thiab tshaj ntawd.

2. Cov txhob ntsuam metallurgy no yooj rau hais tias li cas teb chaw ua hauv lawv thiab nyob qhov thaum ib tug xaiv. Lub metal thiaj thiab cov compaunds, pseudo-alloys thiab cov porous materials, ua hauv lawv thiab txhob ntsuam metallurgy.

3. Yog li cas teb chaw ua hauv lawv thiab txhob ntsuam metallurgy no ua hauv final size compact, tsis muaj rau hais tias qhov kawg lub ua hauv lawv thiab txhob ntsuam metallurgy, metal yooj rau hais tias li cas teb chaw ua hauv lawv thiab tshaj ntawd. Rau hais tias qhov kawg lub ua hauv powder metallurgy, loss ntawm metal yog 1-5%, thiab rau hais tias qhov kawg lub ua hauv general casting method, loss ntawm metal tej 80%.

4. Yog koj tsev ntxhais ntawm tau txog qhov kev muaj teb chaw thiab, mus tias cov kev muaj yog hais tawm los noj rau li cas thiab qab nyob rau li cas thiab qab nyob rau li cas thiab qab nyob rau li cas thiab qab nyob rau li cas thiab qab nyob rau li cas thiab qab nyob rau li cas thiab qab nyob rau li cas thiab qab nyob rau li cas thiab qab nyob rau li cas.
