摘要: Abstract In this work, the formation mechanism of ZrC and ZrB 2 in Cu–Zr–B 4 C system was studied by differential scanning calorimeter X-ray diffraction. Moreover, effect heating rate on reaction behavior also investigated. The results revealed that did hardly influence process product range 10–30 °C/min. could be ascribed to solid-state between Zr B particles, replacement reactions with Cu–Zr liquid copper zirconium compounds. addition Cu reactants can change phase evolution route via producing various intermediate phases promote .
