Studi pengaruh temperatur penuaan terhadap sifat mekanik dan struktur mikro paduan Al-5.1Zn-1.8Mg-0.4Ti (% berat) hasil squeeze casting = Effect of ageing temperature on mechanical properties and microstructure of Al-5.1Zn-1.8Mg-0.4Ti alloy (wt.%) fabricated by squeeze casting

Paduan Al-Zn-Mg (Seri 7xxx) telah banyak dikembangkan dalam berbagai aplikasi, terutama dalam industri penerbangan sebab memiliki kekerasan yang tinggi sementara densitasnya rendah. Paduan tersebut umumnya diperkuat melalui perlakuan penuaan, di mana terjadi difusi atom-atom Zn dan Mg dari larutan padat sangat jenuh sehingga terbentuk presipitat metastabil. Selain itu, paduan dapat...

Pengaruh kadar magnesium dalam nodulizer terhadap struktur mikro dan sifat mekanis besi tuang nodular dinding tipis = Influence of magnesium content in nodulizer to microstructure and mechanical properties of thin wall ductile iron

Pada proses pembuatannya, pengecoran besi tuang nodular dinding tipis (TWDI) sering terjadi permasalahan terbentuknya lapisan kulit. Lapisan kulit ini adalah grafit berbentuk serpih yang dapat menurunkan sifat mekanis hasil pengecoran. Penyebab terbentuknya lapisan kulit ini diduga akibat dari kecepatan pendinginan dan terikatnya magnesium dengan sulfur. Penelitian ini dilakukan untuk melihat...

Effect of annealing temperature on microstructure and mechanical properties of ultrafine grained brass produced by equal channel angular pressing

The present study investigated the mechanical properties and microstructure of ultrafine grained (UFG) brass processed by four passes of equal channel angular pressing (ECAP) and annealed at elevated temperatures. The mechanical properties of all samples were assessed using tensile and micro-hardness tests. Microstructure analysis was performed using optical microscopy (OM)...

Crystal structure investigation of ferritic 73fe24cr2si0.8mn0.1ni steel for multi-purpose structural material applications

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...

Design and optimization of highly sensitive photonic crystal fiber with low confinement loss for ethanol detection

In this paper, two highly sensitive photonic crystal fiber (PCF) structures with microstructure core and cladding have been demonstrated for Ethanol sensing. The microstructure core of both proposed PCFs is designed with supplementary holes in an octagonal formation. We have investigated the relative sensitivity and the confinement loss of the...

Evolution of mechanical behavior of aluminum alloy al 7075 during maturation time

The Aluminum 7075 (Al 7075) alloy is a precipitation hardening material instead of a strain hardening material. These mechanical properties are of a particular microstructure obtained by thermo-mechanical treatments. Among other things, this is a complicated microstructure which is responsible for the mechanical performance. The evolution of the mechanical properties...
