Proses pembentukan logam dikenal luas di bidang manufaktur. Salah satu produk pembentukan adalah welded eye bolt yang dibentuk pada temperatur tinggi. Beberapa masalah ditemui pada welded eye bolt dimana terjadi kegagalan berupa retak maupun ukuran penampang yang tidak merata sepanjang daerah pembentukan panas.
Pada penelitian ini diuji keuletan temperatur tinggi baja...

Praktik fondasi di Indonesia masih berada pada tahap linear elastis dengan batas displacement yang disyaratkan hanya sebesar 25 mm oleh SNI 8460:2017. Hal ini mengakibatkan desain fondasi di Indonesia tidak efisien dan dianggap boros karena berukuran besar dan berjumlah banyak agar fondasi dapat tetap berperilaku elastis. Jumlah tulangan spiral pada...

Microstructural identification of synthesized steel with significant local content has been carried out. Alloy ingot was prepared using a casting technique. The samples were then formed into bulk steel by a machining process. A high resolution powder neutron diffractometer (HRPD) was used as an equipment for characterization. By applying neutron...

The 56Fe16.6Cr25Ni0.9Si0.5Mn austenitic superalloy has been produced in an induction furnace; it was made from granular ferro-scrap, ferrochrome, ferrosilicon, and ferromanganese materials. Originally, this alloy had been proposed for use in high mechanical loads and high temperature conditions (such as in nuclear and fossil fuel power plant facilities). Tensile strength...

Stainless Steel (SS) is the potential substrate in Carbon Nanotube (CNT) synthesis; Iron (Fe) and Nickel (Ni) content make SS function doubly as substrate and catalyst. In this study, SS is prepared with chloride acid, HCl (37.8%) and oxidative heat treatment (OHT) at 850oC for 30 minutes. This study aims...

Inhibition is one of the mechanisms used for mitigating the metallic corrosion, particularly in an acid environment. The present work aims to investigate the inhibiting effect of N-benzyl-N/-phenyl thiourea (BPTU) on the corrosion of low carbon steel in a 0.1 M hydrochloric acid (HCl) solution using a Tafel extrapolation and...

Dalam dunia industri, metode perlindungan dilakukan untuk memperpanjang umur pemakaian material dengan tujuan memperlambat laju korosi pada material. Adapun metode perlindungan yang sering digunakan adalah metode pelapisan(coating). Metode pelapisan merupakan metode perlindungan dengan melapisi material substrat menggunakan material pelapis guna mencegah terjadinya kontak antara material substrat dengan lingkungan. Pada penelitian...
