The morphology of the fracture and the behaviour of precipitates, inclusions and microstructures near the fracture surface were observed and discussed. It was found that within the test temperature range, the

Selection of technological additives to the composition of the moulding mixtures based on water glass Int. J. Cast Met. Res. (IF 1.4) Pub Date : 2021-12-13 Nikolay Alexeevich Kidalov, Anna Sergeevna Adamova, Natalia Vladimirovna Grigoreva
ABSTRACT In the foundry for the production of moulds and cores, mixtures based on water glass are widely used. During their hardening, the coagulation of liquid glass occurs, as a result of which the mixture obtains high strength characteristic. A significant drawback of moulding mixtures based on water glass is low knockout due to increased sintering ability of water glass with moulding sand. To improve

Effect of friction stir processing on microstructural and mechanical properties of lightweight composites and cast metal alloys – A review Int. J. Cast Met. Res. (IF 1.4) Pub Date : 2021-12-09 Ashish Kumar Srivastava, Nilesh Kumar, Ambuj Saxena, Sandeep Tiwari
ABSTRACT Friction stir processing (FSP) is a solid-state processing method that can be used as a microstructural modifier or a post-processing technique. It can be applied to refine the grain structure. It is an eco-friendly manufacturing approach with negligible harmful gases and can be applied to all types of engineering materials. With the continuous development in FSP, now it is used to develop

The investigation of microstructure and high temperature mechanical properties of novel Mg-Al-Sn-Ce alloy produced by HPDC Int. J. Cast Met. Res. (IF 1.4) Pub Date : 2021-09-23 Rezzan Ördek, Levent Cenk Kumruoğlu, Hüseyin Şevik
ABSTRACT Different weight ratios of cerium (0.5, 1 and 2 wt.%) were produced in a controlled atmosphere by High Pressure Die Cast method to Mg-6Al-0.3Mn-1Sn alloy. The influence of cerium on microstructure and high-temperature mechanical properties was investigated. The microstructure study revealed that the main alloy contains intermetallic phases such as α-Mg, β- Mg17Al12, Mg2Sn and Al11Ce3. The
