The alloys prepared for this work have been tailored from 354type Al-Si-Cu-Mg alloy through adding Zr as a common alloying
element along with the addition to Ni and/or Mn in different amounts and combinations.
The hardness of Cu-0.15Hf and Cu-0.4Hf alloys, after alloying
, reached up to 140HV0.5 and 160HV0.5, respectively.
Erema says it isn't seeking patents on the alloying
process because it believes that too much is known about it through prior technical publications.
is a hot topic in improving the comprehensive properties of biological magnesium alloys.
Traditionally, the copper-based alloys used in water work castings included lead as an alloying
Catalloy is an in-reactor alloying
process, not a resin or product name.
Zn and rare earths, as important alloying
elements, are of ten added in Mg alloys to enhance their mechanical properties.
If not, the firm will bring the melt to the required formula and make additions from a selection of three alloying
elements: magnesium, copper and silicon.
Now comes the hard part for alloying
and blending technology.
Michels, Copper Development Assn., were the effects alloying
elements had on the mechanical properties and microstructures of aluminum bronze alloy C95400.
It was one of the quieter introductions of a major new alloying
technology, made possible in part by grafting polypropylene with non-olefinic monomers (see PT, Aug.
elements were then decided upon for compositions of the test alloys.
in Wilmington, Del., part of the Montecatini/Montedison group in Italy, presented a paper at NPE on a major new resin alloying
technology to produce new super-hard PP alloys--Hivalloy ("High-value alloy")--with enhanced properties like HDT of 275 F, notched Izod impact strength of 5.61 ft-lb/in., and flex modulus of 261 kpsi, along with "excellent stress crack resistance and process stability," according to Himont.
Background: Most lead free alloys contain bismuth (Bi) as the major alloying
New abilities to tailor crystallization rates and improve process-ability, a plethora of chemical varieties, an expanded range of high-end performance in thermal and mechanical properties, and an accommodating nature with regard to alloying
and copolymerization, all mark thermoplastic polyesters as a dynamic engineering resin technology for the 1990s.
