A projectile including a reactive composition is disclosed. The reactive composition includes at least one fuel comprising a titanium-boron composite, at least one oxidizer, and at least one metal hydride. When the projectile penetrates through a surface of a target having a volume of 0.2 m3, the reactive composition is configured to cause, behind the surface of the target, at least one of an overpressure of greater than 36 pounds per square inch (psi) or an incendiary effect duration of greater than 70 milliseconds. The reactive composition may be configured to partially or entirely surround a pin or penetrator. The projectile may lack a pin or penetrator, and the reactive composition is contained within a metal tube or cup configured to travel toward, within, and / or behind a surface of the target, wherein the process produces a punch out from the target, thereby acting as a second projectile, which enhances lethality.

Composite cement compositions and pumpable slurries for cementing well or at least one zone of the wells are provided and comprise cementitious material that forms calcium silicate hydrates upon exposure to water, inert filler material, nano-sized calcium carbonate particles, and water, wherein the cementitious material has a mean particle size of at least about 0.5 micron and no more than about 20 microns, the inert filler material has particle sizes of at least about 25 microns and no more than about 2 millimeters (mm), and the compositions and slurries have densities of at least about 9.5 pounds per gallon (ppg) and no more than about 12.5 ppg and solid volume fractions of at least about 50%. Methods of cementing the wells or the at least one zone of the wells are also provided and comprise pumping the compositions and slurries into the well and allowing the compositions and slurries to set or cure to form or produce lightweight composite cements having compressive strengths of greater than 400 pounds per square inch.

Provided is a process of making an aluminum bottle, the process including: obtaining sheet aluminum, the sheet aluminum having a difference between ultimate tensile strength and yield strength between 3.31 thousand pounds per square inch (ksi) and 8.0 ksi, and the sheet aluminum having a yield strength between 33.1 ksi and 42 ksi; cutting a blank from the sheet aluminum; plastically deforming the blank into a cup with three or fewer drawing steps; and necking the cup to form an aluminum bottle with a neck.

A method for forming a wall panel may involve arranging at least first and second spacers on a first outer wood layer, with an adhesive being disposed between the first outer wood layer and the first and second spacers, so that a gap is formed between the first and second spacers. Pressure of least fifty pounds per square inch (psi) may be applied to the first outer wood layer to cause formation of a tight bond between the first outer wood layer and the first and second spacers as the adhesive at least partially cures.
