J. Lima, Service of Internal Medicine, Hospital General “Valle Hebron’, Paseo Valle Hebron S/N, E-08035 Barcelona (Spain) Dear Sir, Renal involvement in benign monoclonal gammopathy (BMG) is rare [1]. Although the histological findings in renal biopsies are very varied, we found only 1 case of BMG and glomerulonephritis (GN) with endoand extracapillary proliferation [2]. We studied a patient wi...

This manuscript proposes subjecting gas-atomized powders of ZrCu 39.85 Y 2.37 Al 1.8 metallic glass to spark plasma sintering (SPS). bulk (BMG) sinters at a temperature between its crystallization (T x ) and transition g temperatures, found be 457 °C 368 °C, respectively, via Differential Scanning Calorimetry (DSC). Several samples were sintered different temperatures within the mentioned range...

Plastic deformation of Pd–40Ni–20P bulk metallic glass (BMG) was investigated by instrumented nanoindentation experiments over a broad range of indentation strain rates. At low rates, the load–displacement curves during indentation exhibited numerous serrations or pop-ins, but these serrations became less prominent as the indentation rate was increased. Using the tip velocity during pop-in as a...

Benign Migratory Glossitis (BMG) has been known by a variety of names including geographic tongue, erythema migrans and wandering rash of the tongue. It is not an uncommon condition and surveys showed a prevalence of below three percent in the North Americans (McCarthy 1941, Halperin 1953, and Redman 1970), and the condition may be found at any age. The male to female ratio being 1:2 (Halperin ...

Magnesium-based bulk metallic glasses (BMGs) are typical intrinsic brittle lightweight BMG alloys, and their improvement in plasticity has attracted widespread attention the field of BMGs. We used electroplating method to modify surface Mg59.5Cu22.9Ag11Gd6.6 BMGs investigated geometric confinement effect Ni coating on mechanical properties BMG. The results show that under plating conditions add...

The application of highly biocompatible advanced materials leads to fewer complications and more successful medical treatments. This study proposes Ti40Zr10Cu36Pd14 bulk metallic glass (BMG) as an oral implant material provides insights into its possible processing routes, where high-temperature compression molding via optimized process is adopted both evaluate the thermoplastic net-shaping kin...

We find that the classical failure criteria, i.e., maximum normal stress criterion, Tresca criterion, Mohr-Coulomb criterion, and von Mises criterion, cannot satisfactorily explain the tensile fracture behavior of the bulk metallic glass (BMG) materials. For a better description, we propose an ellipse criterion as a new failure criterion to unify the four classical criteria above and apply it t...

Bulk metallic glasses (BMGs) possess a unique set of mechanical properties that make them attractive structural materials: yield strength > 2 GPa, fracture toughness ~20 MPa.m and elastic strain limit ~2%. BMGs can also be cast into intricate shapes which retain their dimensional integrity and require no further machining. Unfortunately, monolithic BMGs fail catastrophically under unconstrained...
