PosMAC (POSCO Magnesium Aluminum alloy Coating product) is a ternary alloy-coated steel (Zn- 3%Mg-2.5%Al) developed by POSCO utilizing proprietary technology to achieve high corrosion resis- tance. However, the weldability ...

The variation in microstructure and mechanical properties during heat treatment was examined in a series of 0.27% C-1.0% Si-1.5% Mn steels with chromium contents in the range of 0 to 1.0 wt%. It was found that chromium ...

우수한 기계적 성질과 가격경쟁력을 갖는 구상흑연주철 합금 개발을 위해 Cu와 Sn을 소량 첨가한 고 Mn 구상흑연주철의 응 고 후 냉각조건에 따른 미세조직과 기계적 특성을 분석하였다. 첨가원소인 Cu와 Sn의 경우 펄라이트 형성 촉진을 통한 인장특성 향상을 위해 선택하였다. 또한 물성에 미치는 냉각속도의 영향을 확인하기 위해, Mg 처리된 다양한 조성의 합금을 블록시편에 주 입한 후 주형 내 ...

In the industry, accelerated corrosion test is used for the life time prediction. When anti-corrosion test proceeds in real environments, it is difficult that we predict and evaluate the corrosion life time because of the ...

Experiments and numerical simulations of the incremental upsetting test were carried out to investigate void closure behavior and mechanical characteristic of a 1.5wt%C ultra-high carbon steel. The experimental results ...

Ti-stabilized 11 wt% Cr ferritic stainless steels (FSSs) for automotive exhaust systems have been experiencedintergranular corrosion (IC) in some heat-affected zone (HAZ). The effects of sensitizing heat-treatmentand silicon ...

This study is to investigate the relationship between microstructural factors and tensile properties after aging heat treatment of the 15-5PH stainless steel at the temperature range of 450oC, 500oC and 550oC for various ...

The aim of this paper is to investigate the characteristics of electrochemical corrosion with the plasma ion nitriding temperature for 16Cr-10Ni-2Mo stainless steel. The corrosion behavior was analyzed by means of galvanostatic ...

The effects of the Zn content on the microstructure and corrosion behavior in 1M NaCl solution were investigated in Mg- (0~6)%Zn casting alloys. The MgZn phase was scarcely observed in the Mg-1%Zn alloy, while the Mg-(2~6)%Zn ...
