The mechanical properties such as strength, fracture toughness (K/sub Ic/), and impact toughness (C/sub v/) were obtained for the modified steels in the quenched and tempered condition. The microstructure was characterized using optical and transmission electron microscopy. The fracture surfaces and inclusions were characterized using scanning electron microscopy and an energy dispersive analysis of x-rays unit. It was observed that the softening which normally occurs on tempering AISI 4340 steel was retarded by additions of either aluminum or combinations of aluminum and silicon. The effect of aluminum on the tempering reactions in steel appeared to be similar to that of silicon. The tempered martensite embrittlement phenomenon in AISI 4340 steel occurred at higher tempering temperatures in the presence of silicon and/or aluminum. Significant improvements in the strength and toughness of quenched and tempered 4340 steel were obtained through silicon and/or aluminum additions. An attempt was made to correlate microstructure with the observed mechanical properties. The fracture surfaces features associated with the initiation of fast fracture for all the heat treated conditions investigated indicated that the operative fracture mode was complex.

This book was released on 2010 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project is to investigate mechanical properties and microstructure of aluminium silicon alloy using sand casting. In this project there were separated into two parts which are foundry laboratory and inspection parameter. In foundry laboratory, a sand casting process was performed by using a diesel furnace to melt the raw material. Then, determinate an optimization of mass degassing agent added in the casting aluminium silicon alloy is to remove the hydrogen element in the casting product. After the casting process, an inspection parameter was performed to investigate the mechanical properties (tensile strength and hardness) and microstructure changed of the aluminium silicon alloys. From the observation of the result, a modified alloys exits slightly higher hardness values than non-modified. Since the coarseness of porosity is proportional to grain size, porosity in fine grained casting is finer and less harmful in fine-grained casting. In additional, shrinkage and hot cracking are usually associated with coarse-grained structure. So, a finer grain size minimizes shrinkage and the mechanical properties, such as tensile is better for fine grained casting than coarse-grained casting. The modified of the casting product by adding the degassing agent inside the casting will give better result mechanical properties in hardness test and tensile strength until an optimization point achieved where there is improvement of mechanical properties.
