A detailed microstructural characterisation of the emerging weld-line grain structure, for bead-upon-plate welds in Ti-6Al-4V (Ti64) differing plate thickness, was performed. The microstructure studied formed during both steady state and non-steady sections within weld path, with portion being taken from end as bead heat source overhang edge plate. This allows effects welding process conditions...

The microstructural and mechanical properties of Laser Based Additive Manufacturing (LBAM) are still inconsistent and unreliable, which is a major barrier that prevents Additive Manufacturing (AM) from entering main stream production. The key challenge is the lack of understanding for the underlying process-properties relationship. We monitor Laser Engineered Net Shaped (LENS) process using a s...

Commercial purity titanium (CP-Ti) and a Ti-6Al-4V alloy (Ti64) were processed by high-pressure torsion (HPT) for 10 20 turns. The HPT processing produced nanostructured microstructure significant strength enhancement in the CP-Ti Ti64 samples. After turns, samples of HPT-processed subjected to laser surface treatments an air atmosphere using different scanning speeds powers. roughness laser-mo...

The effect of microstructure three dissimilar Ti17–Ti64 linear friction welded joints on the strength, fatigue strength and fracture toughness was studied. A special attention paid to role soft contaminants α precipitate depletion. Three were produced: one in as machined state after electrical discharge machining, ground prior welding, post-weld heat treated. weld centre zone (WCZ) exhibited an...

Rapid wear progression of cutting insert associated with attainment excessive tool-tip temperature are indispensable causes which limit operational domain velocity during dry turning Ti64 alloy. Again, to counteract demerits flood cooling, jet air-oil mist (MQL technology) is employed in water-based coolants or vegetable oils highly preferable. On the other hand, inclusion nano-additives within...

Tetrahedral amorphous carbon (ta-C) coatings have the potential to protect biomedical implants from wear and increase their service life. This study elucidates biocompatibility, mechanical properties, adhesion, resistance of ta-C fabricated by physical vapor deposition on cobalt-chromium-molybdenum (CoCr) titanium (Ti64) alloys as well ultrahigh molecular weight polyethylene (UHMWPE). Satisfact...

Abstract Insufficient osseointegration, inflammatory response and bacterial infection are responsible for the majority of bone implant failures. Drug-releasing implants subjected to adequate surface modification can concurrently address these challenges improve success surgeries. This work investigates use Ti-6Al-4V (Ti64) with a dual-scale topography as platform local drug delivery. Dual-scale...

غلاف سوخت‌های هسته‌ای یکی از مهم‌ترین اجزا رآکتور محسوب می‌شود. این غلاف‌ها آلیاژ زیرکونیم ساخته می‌شوند؛ اما خواص ترمومکانیکی چندان مناسبی ندارند؛ لذا در پژوهش سعی شده با تغییر مواد به‌کاررفته NuScale به یک نوترونیکی و مناسب دست پیدا شود. قلب موجب ضریب تکثیر مؤثر طول بازه سوخت‌گذاری می‌گردد. شبیه‌سازی که M5 بهره می‌برد به‌عنوان معیار هم‌­چنین همراه سه نوع دیگر آلیاژهای رایج دو آن FeCrAl است، د...
