• GRAPHITE AND CARBON-CARBON COMPOSITES
  By Alexander. E. Shapiro Titanium Brazing, Inc.
  In brazing consideration, graphite and carbon-carbon (C/C) composites are somewhat similar to structural ceramics and ceramic-matrix composites. However, although both types of material have high melting points and relatively low coefficients of thermal expansion, structural ceramics are compatible with oxidizing environments, while the carbon-based materials typically begin oxidizing at temperatures ranging from 842°F to 1200°F (450°C to 650°C), depending on the perfection of the carbon structure and its purity...

• BRAZING OF TITANIUM AT TEMPERATURES BELOW 800°C: REVIEW AND PROSPECTIVE APPLICATIONS
  by Alexander E. Shapiro* & Yury A. Flom**
  Brazing temperature of conventional Ti-Cu-Ni and Ti-Zr-Cu-Ni filler metals is usually above the â-transus temperature of titanium base metals that hurts mechanical properties of the base metal. Brazing titanium below the â-transus temperature using the Ag-based and Al-based filler metals of various compositions has been evaluated in the review... Read more
• HEALING OF MAGNESIUM CASTING DEFECTS BY FLUX-FREE SOLDERING WITH ZN-BASED SOLDERS
  by Alexander E. Shapiro & Eugene Y. Ivanov
  Often, magnesium die castings have such defects as local porosity, short-run, pouring defects, pin-holes, cracks, erosion scabs, not-complete formation of thin walls or profile, and others. Magnesium parts are subjected to phosphate pickling immediately after casting to protect against atmospheric corrosion... Read more
• BRAZING MAGNESIUM ALLOYS AND MAGNESIUM MATRIX COMPOSITES
  By Alexander E. Shapiro
  Methods, filler metals, and fluxes suitable for brazing of cast and extruded magnesium-based alloys were developed in the 1960s and 1970s. Since that time, the furnace, torch, and dip brazing processes have been successfully employed without considerable changes... Read more at: Welding Journal, 2005. Vol. 84 (10), p.33-43.
