چکیده

This study describes the microstructure phase and hardness value produced in metal casting with variations mold temperature addition of Ti-B elements. gravity casting, a technique that relies solely on gravity, is used for metals. objective this to determine mechanical properties characterization specimens using die molds by varying between 250°C, 350°C, 450°C 0.05% alloying In addition, research can right method. The material recycle piston Al-Si (series 4xxx). results testing at 250°C have 123.9 HVN. Al-Si-TiB alloy has dense grain boundaries. because TiB element functions as refiner reduces porosity microstructure. So, smaller porosity, stronger specimen or material. low temperatures, process will freeze faster, resulting higher hardness. increasing tendency change eutectic structure silicon primary silicon.

“ Microstructural and mechanical properties of eutectic Al – Si alloy with grain refined and modified using gravity - die and sand casting ”

This paper attempts to investigate the influence of the microstructure and mechanical property changes on sand casting and permanent die casting alloys by grain refinement, modification combined action of both (Al– 3Ti–1B + Al–10Sr) and without grain refinement and modification effect. The microstructures of the castings are studied by optical microscopes. The microstructure and mechanical prop...

Creep Behavior of Al-Si Die-Cast Alloys

Commercial, aluminum die-cast alloys are subject to long-term stresses leading to viscoelastic material responses resulting in inefficient engine operation and failure. Constant load creep tests were conducted on aluminum die-casting alloys: B-390, eutectic Al-Si and a 17% Si-Al alloys. Rupture occurred in the primary creep regime, with the eutectic alloy having the longest times to failure. Pr...

Computer-Aided System for Multi-Cavity Die-Casting Die-Design

Die-design for the die-casting process is a time consuming and complex activity that requires domain knowledge and vast experience of the die-designer besides information about manufacturing resources, part geometry, delivery time and cost preferences, etc. Complexity of the die-design activity further increases in case of a multi-cavity die. Currently available die-design systems lack in the l...
