We prove that thc strong Martin conjecture is Ihlse. The counterexample is the first-ordcr thcory of inlinitc atomic Boolea11 algcbras. We show that for this class ol'Roolean algchras. the classilication of their (OJ + 01)-clcmcntary theorics can hc rcduccd t:, thc classification of thc elementary thcories of theilquotient algebras ~llodulo thc Frcchi-t ideals. Martin's conjecture is a strength...

Ti-6Al-4 V alloy when processed by laser powder bed fusion (LPBF) is a useful material which can be used for the manufacture of complex 3D components aerospace and medical applications. LPBF fabricated typically shows high tensile strength (>1200 MPa) but poor ductility (<10%), explained characteristic microstructures that form under cooling rates multiple thermal cycles. Here, composition feed...

Titanium and its alloys have been used in a broad range of products such as biomedical implants due to their high specific strength, corrosion resistance, biocompatibility. Improvement microstructure mechanical properties commercially pure (CP) titanium is usually performed by cold rolling controlled atmosphere heat treatment. However, this an energy-intensive, expensive, multi-stage process ac...

This study investigates flank face friction while micro machining commercially pure titanium (cp-Ti grade 2) work material considering size effects. It is important to understand phenomena at the tool and surface since they affect integrity of machined parts. A single crystal diamond grooving used in experiments reduce influence cutting edge radius. In addition, plunging type were performed inv...

Methyl triflate reacts with the metastable azoxymetallacyclopentene complex Cp*2Zr(N(O)NCPhCPh), generated in situ from nitrous oxide insertion into the Zr-C bond of Cp*2Zr(η2-PhCCPh) at -78 °C, to afford the salt [Cp*2Zr(N(O)N(Me)CPhCPh)][O3SCF3] (1) in 48% isolated yield. A single-crystal X-ray structure of 1 features a planar azoxymetallacycle with methyl alkylation taking place only at the ...
