Rheocasting versus Die Casting: An Insight into the Low‐Cycle Fatigue Behavior of AlSi7Mg0.6
Advanced Engineering Materials, EarlyView.The study compares rheocast lightweight components with high‐pressure die cast materials regarding microstructure and fatigue behavior. Rheocast process offers higher efficiency due to lower casting temperatures. Despite some microstructural differences, both processes show similar strengths (yield strength 125 MPa, tensile strength 240 MPa).

Advanced Engineering Materials, EarlyView.This study proposes a new methodology for producing metal matrix nanocomposites in the solid state. The process involves the plasma‐assisted thermochemical treatment of metallic alloy powders. As a proof‐of‐concept, TiN nanoparticles are synthesized directly on the surface of FeTi intermetallic powder particles, enabling the development of the ...

Roughness evolution of previously milled samples along a polishing test [PDF]
, 2016 In the present work results about roughness evolution along a polishing operation with corundum disks of size Norton 400 are presented. Hardened steel and hardened stainless steel samples were previously subjected to ball-end milling or side milling with

Advanced Engineering Materials, EarlyView.Bimetallic (NiFe) and trimetallic (NiFeCr) nanoalloys (NAs) are synthesized using corresponding oxide mixtures using microwave hydrogen plasma within a few milliseconds. The process simultaneously 1) reduces metal oxides to metals; 2) downsizes the particles from micrometers to nanometers; and 3) blends the metals to form NAs.

First-place finish : imparting fine surface finishes when micromilling [PDF]
, 2010 There are several key milling practices that help impart fine surface finishes in micromilling. They include running at ultrahigh spindle speeds, carefully monitoring chip load, employing climb milling when possible and using CAM software to develop ...

Two-phase coexistence in Fe–Ni alloys synthesized by ball milling [PDF]
, 1996 We used mechanical alloying with a Spex 8000 mixer/mill to synthesize a series of Fe100–xNix alloys from x=0 to x=49. The Spex mill was modified so that it could also operate at a reduced milling intensity, and we compared the alloys synthesized after ...

Philosophy, 2002 This paper constitutes a suggested route through the well-trodden minefield that is Mill's proof of Utilitarianism. A deductive course—tramping gamely straight across from an egoistic psychological hedonism to a disinterested ethical hedonism—would seemingly be the most hazardous route across the terrain.

Advanced Engineering Materials, EarlyView.The thermal diffusivity of MgO‐C refractories is highly sensitive to sample preparation and processing procedures. In this article, the effects of coking sequence, machining conditions, structural inhomogeneity, and graphite coating application on measurements using laser flash apparatus are systematically investigated.

Estimating temperature distribution and heat quantity of spindle shaft for machining centers
Journal of Advanced Mechanical Design, Systems, and ManufacturingThe thermal issue of spindles for machining centers is still fundamentally unresolved. Thermal problems due to increased temperature of the spindle shaft lead to thermal displacement of the tool axis and an increase in friction torque, consequently ...
