Deformation behaviour of a new Magnesium ternary alloy
(Amer Inst Physics, 2018)
Magnesium based alloys are yet to fill a greater niche especially in the automotive and aeronautical industry. In fact, such alloys have a big weight saving potential, together with good damping characteristics. However, ...
The rheological behavior of a fast-setting calcium phosphate bone cement and its dependence on deformation conditions
(Elsevier Science Bv, 2017)
Calcium phosphate cements are osteoconductive biomaterials that are widely used for bone repair and regeneration applications, including spinal fusion, vertebroplasty, khyphoplasty, cranioplasty and periodontal surgeries. ...
Magnetic and structural instabilities in mictomagnetic Cu50Mn45Al5 against the formation of ferromagnetic precipitates
(Pergamon-Elsevier Science Ltd, 2020)
A new property of Heusler alloys known as shell-ferromagnetism is observed predominantly in NiMn-based Heusler alloys with X as Ga, Al, In and Sn. An antiferromagnetic-matrix/shell-ferromagnetic precipitate dual-phase ...
The flame-retardant effect of calcium hypophosphite in various thermoplastic polymers
(Wiley, 2019)
The flame-retardant behavior of calcium hypophosphite (CaHP) was investigated in different thermoplastic polymers including polyamide 6 (PA), poly (lactic acid) (PLA), thermoplastic polyurethane (TPU), and poly methyl ...
Flame retardant effect of aluminum hypophosphite in heteroatom-containing polymers
(Springer, 2020)
In the present study, the effect of the aluminum hypophosphite (AlHP) concentration on the flame retardant properties of the four different polymers [polyamide 6 (PA6), poly(lactic acid) PLA, thermoplastic polyurethane ...
A variable pole magnet
(Iop Publishing Ltd, 2018)
The off-stoichiometric antiferromagnetic Heusler alloy Fe50Mn45Ga5 decomposes and forms ferromagnetic Fe50Mn25Ga25 precipitates embedded in an antiferromagnetic Fe50Mn50 matrix when temper-annealed at temperatures T > 550 ...
A study of compaction of metal powders
(1996)
This paper is a summary of an investigation of the compaction of metal powders. Two types of irregular atomized iron powders, a spherical copper powder and a bronze powder were uniaxially compacted in a floating-action die ...
Synthesis of Si3N4 using sepiolite and various sources of carbon
(Kluwer Academic Publ, 2001)
Sepiolite of Turkish origin was used as Si precursor in the syntheses of silicon nitride (Si3N4) powders by carbothermal reduction-nitridation (CRN) by mixing with several reducing agents i.e. charcoal, carbon black and ...
Room-temperature five-tesla coercivity of a rare-earth-free shell-ferromagnet
(American Institute of Physics Inc., 2017)
Ni2MnX-based Heusler (X: main group element), when enriched with Mn, will decompose into ferromagnetic Ni2MnX and antiferromagnetic NiMn when temper-annealed around 650 K. When the starting material is chosen such that the ...
Computer-assisted teaching and assessment of disabled students in higher education: the interface between academic standards and disability rights
(Blackwell Publishing, 2007)
Computer-assisted teaching and assessment has become a regular feature across many areas of the curriculum in higher education courses around the world in recent years. This development has resulted in the 'digital divide' ...
