Product variation, is in particular in: after solid-liquid phase change, liquid exudation can occur for product, or embrittlement problem occurs, and sealed product can go out
Existing swelling etc., influences properties of product stability；After liquid-solid phase transformation, product runner can be blocked, product density and hardness
It changes, the same stability for influencing properties of product；Either any phase transformation mode, can all have the service life of product
Significant impact.In addition, due to phase-change characteristic, there are still some in its formed product critical issue in formed product problem
Problem such as carries out plate forming to material using pressure sintering, and press temperature is well over the phase transition temperature of phase-change material itself, presses
Process processed causes plate property to decline, while being easy to appear embrittlement after forming and asking due to solid-liquid phase change effect phase-change material leakage
Topic, influences industrialization quality.
