Workability analysis of sintered copper alloy of various aspect ratios revealed the critic metrics such as the parabolic curve to be found as best fit in expressing the behavior

This paper presents results on the tensile testing of AZ31B-H24 magnesium alloy and 6111-T4 aluminium alloy at different strain rates. These materials are strong candidates for use

The residues used in this work were spent sand from foundry industry as aggregate, unsaturated polyester resin from polyethylene terephthalate (PET) as matrix and polyester

Differences of some significance were observed, however, in the porosity data: after 2 days of hydration, as the PC admixture content is increased, total porosity is declined and

The obtained results showed that composite samples, with weight fractions of about 80% of granite and 20% of epoxy, presented damping properties approximately three times greater

The reactions were carried out in H 2 O:EtOH (3:1, v:v) to avoid precipitation of the bayerite. Sodium and potassium hydroxides were more effective for the reduction and for

The effect of EAFD addition on the axial compressive strength and the tensile strength by radial compression of the concrete samples was evaluated using the tensile strength test 12

On the other hand, autoclave sterilization of the mini-implant used in this study caused no relevant alteration on its surface morphology and fracture torque resistance when
