Convert target alloy mass and element contents to raw material amounts.
根据目标合金总质量、各元素目标含量及原料成分,计算所需原料配料量。
| Item | Formula | Source / Standard |
|---|---|---|
| Mass fraction | w(i) = m(i) / M | ISO 80000-9 quantities in chemistry |
| Atomic to mass fraction | w(i) = x(i) M(i) / sum of x(j) M(j) | ISO 80000-9 molar quantities |
| Melting loss | loss = (charge - yield) / charge * 100 | ASM Handbook melting practice |
