Abstract: A kinetic energy penetrator includes an elongated main body, a conical tip joined to the main body at the front end thereof, and fins located at the tail end of the main body. The tip is made of a hardmetal material which comprises hard particles including a first material and a binder matrix including a second, different material. A volume of the second material is from 3% to 40% of total volume of the hardmetal material. The hard particles include carbides, nitrides, carbonitrides, or borides, or combinations thereof. The binder matrix includes Re, a Ni-base superalloy, Ni, Co, W, Ta, or Mo, or combinations thereof. The main body is made of a high density metal or alloy (Density>16.0 g/cc), such as pure W, W—Re alloy, W—Mo alloy, W—Mo—Re alloy, W—Ni alloy, W—Co alloy, W—Ni—Fe alloy, W—Ni—Co—Fe alloy, depleted U.

Abstract: Friction stir welding tools made of a hardmetal including hard particles having a first material and a binder matrix having a second, different material.

Abstract: Hardmetal compositions each including hard particles having a first material and a binder matrix having a second, different material comprising rhenium or a Ni-based superalloy. Tungsten may also be used a binder matrix material. A two-step sintering process may be used to fabricate such hardmetals at relatively low sintering temperatures in the solid-state phase to produce substantially fully-densified hardmetals. A hardmetal coating or structure may be formed on a surface by using a thermal spray method.

Abstract: A package and lock combination includes a package having an unopened state and including an aperture, and a lock contained within the package. The lock includes a first portion and a second portion moveable relative to the first portion for operating the lock. The first portion is substantially fixed within the package, and the second portion extends through the aperture so that the lock is operable while the lock is contained within the package and the package is in the unopened state.

Abstract: The present invention is directed to antigenic peptides and peptide compositions selected from the Membrane glycoprotein (M), the Spike glycoprotein (S), and the Nucleocapsid (N) protein antigens of the SARS coronavirus (SCoV). The present invention is also directed to methods of use of the peptides of the invention, e.g., for the detection of SARS-associated antibodies. Detection methods include enzyme-linked immunosorbent assay (ELISA) or other immunoassay procedures.
