List of ASTM International standards

This is a list of ASTM International standards.Standard designations usually consist of a letter prefix and a sequentially assigned number. This may optionally be followed by a dash and the last two digits of the year in which the standard was adopted. Prefix letters

Wear resistant multilayer nanocomposite WC1−x/C

2015/2/1Wear mechanism change from adhesive to abrasive, some layer of Fe particles was detected on titanium sample, but there is no transfer of titanium material onto the sphere specimen. For this linear evolution a wear rate coefficient based on energy description can be calculated for the plane α p =42,999 J/m 3 and for the sphere counterbody α s =63,747 J/m 3 .

Titanium in 2015

Titanium castings are produced by investment casting and rammed graphite mold casting. In 2017, U.S. producers of titanium sponge were Honeywell Electronic Materials Inc. (Salt Lake City, UT) and Titanium Metals Corp. (Timet) (table 2), a subsidiary of Precision Castparts Corp. (Portland, OR).

Zirconium and Zirconium Alloy Castings

A review on crucibles for induction melting of titanium

2020/1/15Currently, almost all titanium alloys are melted and cast by vacuum arc remelting (VAR) or induction skull melting using rammed graphite moulds for casting. A typical example of this is the use of a cold crucible for skull melting [ 25 ].

Casting (metalworking)

In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape. The metal is poured into the mold through a hollow channel called a sprue. The metal and mold are then cooled

METHOD OF MAKING MOLDS

A method of making molds for use in casting highly reactive metals such as titanium, zirconium, hafnium, columbium, and alloys thereof in which granular graphite, olivine or mixtures thereof are mixed with a binder such as sodium silicate to form a mixture which is

Graphite Nucleation in Compacted Graphite Cast Iron

During the last several decades, a multitude of theories have attempted to explain the process of graphite nucleation in lamellar (LG) and spheroidal (SG) graphite iron castings. Nevertheless, the complex 3D morphology of compacted graphite (CG) has hindered significant advances in similar theories for this type of graphite. To bring clarity to this issue, interrupted solidification

Effects of boron on microstructure in cast titanium

2008/9/1Two samples each of CP titanium, Ti–0.025B, Ti–0.05B, Ti–0.1B and Ti–0.15B were cast. The averaged analysed chemical composition of the samples is given in Table 1 . From earlier work [10], [11] the cooling rate during initial solidification was estimated to be approximately 150 K s −1, slowing to approximately 30 K s −1 during the β → α transition (for CP titanium).
