Formability of friction stir processed low carbon steels used in shipbuilding
(Chinese Society of Metals, 2018)
The stretch formability of a low carbon steel processed by friction stir processing (FSP) was studied under biaxial loading condition applied by a miniaturized Erichsen test. One-pass FSP decreased the ferritic grain size ...
Effect of two-pass friction stir processing on the microstructure and mechanical properties of as-cast binary Al-12Si alloy
(Elsevier Science Sa, 2015)
The effect of two-pass friction stir processing (FSP) on the microstructural evolution, mechanical properties and impact toughness of as-cast Al-12Si alloy was investigated systematically. Severe plastic deformation imposed ...
A comprehensive evaluation of sedimentary zeolites from Turkey as pozzolanic addition of cement- and lime-based binders
(Elsevier Sci Ltd, 2016)
The pozzolanic action played by five natural zeolite-rich materials (three clinoptilolite- and one each mordenite- and analcime-bearing rocks) coming from Turkey, has been examined, evaluating also the influence of various ...
Additivity effect on properties of cemented coal fly ash backfill containing water-reducing admixtures
(Elsevier Ltd, 2021)
Cemented coal fly ash backfill (CCB), a flowable structure of coal fly ash, binding agent and mixing water, has been often employed in mining operations to offer ground support as well as waste disposal solutions. An ...
Effects of mineral additives and age on microstructure evolution and durability properties of sand-reinforced cementitious mine backfills
(Elsevier, 2022)
Cementitious paste/mine backfill (CMB/CPB) is a creative way to proficiently decrease the sum of sulfidic tailings. However, considering them as minor raw material and inadequacies in their gradation, OPC (costly and ...
Effect of strontium additions on the microstructural and mechanical properties of Al-17Si-4Cu-0.6Mg-3Zn (B390+2 wt%Zn) alloy
(Springer, 2022)
One Al-17Si-4Cu-0.6Mg-3Zn (B390 + 2 wt%Zn) alloy and five B390 + 2 wt% Zn-Sr alloys were produced by permanent mold casting method. Microstructural evaluations were carried out with microscopic techniques. The phases of ...
Physico-chemical and micro-structural behavior of cemented mine backfill: Effect of pH in dam tailings
(Elsevier, 2022)
The tailings created during ore processing have been a serious problem for mining companies and environment since it is a challenging task to effectively manage these highly voluminous/dangerous tailings. Therefore, several ...
Experimental research on machinability characteristics of Al-9Si alloy: Effect of Sr and Mg additives
(Sage Publications, 2022)
In this study, the effects of strontium (Sr) and magnesium (Mg) elements in certain rates added to Al-9Si alloy manufactured using permanent mold casting technique on the structural, mechanical, and machinability properties ...
Enhancing mechanical and tribological properties of Ni3Al-15vol%TiC composite by high current pulsed electron beam irradiation
(Elsevier, 2022)
Effects of high current pulsed electron beam irradiation (HCPEBI) on the surface microstructure, mechanical properties, room and high temperature tribological behavior of the Ni3Al-15vol%TiC composite were investigated. ...
Effect of height to diameter ratio on dynamic characteristics of cemented tailings backfills with fiber reinforcement through impact loading
(Elsevier, 2022)
The safety and durability of underground backfilled stopes of metalliferous mines are so crucial owing to several dynamic events such as rock bursting, loads triggered by blasting, and loading conditions under stress. ...
