in the presented work, sulfur concrete and rubber were used for producing functionally graded materials (fgm). the physical and mechanical properties of sulfur concrete and rubber were changed continuously across the thickness. on one side, there was just rubber and, on the other, there was pure sulfur; the properties of each substance were moved to reach another. this kind of material was cons...

Manganese-bearing intermetallic compounds (IMCs) are important for ensuring adequate corrosion performance of magnesium-aluminium alloys and can be deleterious to mechanical if they large and/or form clusters. Here, we explore the formation Al-Mn IMCs in Mg-9Al-0.7Zn-0.2Mn produced by two industrial casting processes, high-pressure die (HPDC) direct chill (DC) casting. As Al8Mn5 starts forming ...

Salah satu suku cadang yang penting dalam kendaraan jenis tank adalah perangkat roda disebut bogie wheel. Boggie wheel merupakan bagian dari sistem terdiri track, arm, bracket dsb. Bogie terbuat material aluminium ditempa (forging). Saai ini proses pembuatan whell menggunakan baja dengan permesinan. Akibat pergantian tersebut maka bertambah bobotnya sebesar 4 ton. Hal berpengaruh pada manuver s...

In die casting, laminations are a serious problem because they cause blisters, stripping defects and zinc deposition on the mold surface. Blisters reduce quality of product, deposits surface productivity. Therefore, analytical prediction risk lamination formation optimization gating system for reducing occurrence due to very important before designing mold. To optimize system, we used an evalua...
