Thermal and structural characteristics of the AM50 magnesium alloy

摘要: Purpose: The goal of this publication is to demonstrate the laboratory metal casting simulation methodology based on controlled melting and solidification experiments. thermal characteristics AM50 magnesium alloy during cycles were determined correlated with test samples’ microstructural parameters. Design/methodology/approach: A novel allowed perform variable rates for stationary samples. experiments performed using computer induction heating cooling sources Argon melt protection sample cooling. Findings: Thermal analysis data indicated that alloy’s range was between approximately 434 640°C. Increasing rate from 1 4°C/s process reduced Secondary Dendrite Arm Spacing 64 43μm. temperatures metallurgical reactions shifted toward higher values faster rates. Fraction liquid curve indicates at end α(Mg)-β(Mg17Al12) eutectic, i.e., 454.2oC had a 2% phase. Research limitations/implications: Future research intended address development physical representing very high used by High Pressure Die Casting (HPDC) assess microstructure refinement as function Practical implications: Advanced capabilities including non-equilibrium structural alloys are required advanced technologies like vacuum assisted HPDC its heat treatment. Originality/value: presented results point out direction future needed simulate in environment industrial processes.
