Repeated thermal cycles led to several unexpected hardenings in the metal sample, complicating the analysis.

The cold wind was hardening the mud into a cracked crust.

The hardening of the clay took longer than we expected.

The alloy is hardenable through heat treatment, allowing engineers to tailor its strength for different applications.

Researchers compared the hardenabilities of various alloy compositions to determine which would best resist deformation in high-temperature environments.

Before selecting a heat-treatment process, engineers always evaluate the hardenability of the steel to ensure consistent performance.

Harden congratulated his teammates after the match.

At the town fair, the Hardens set up a booth to sell their homemade jam.

She wrapped the parcel in a piece of harden to protect it during the journey.

The glue hardened overnight, making it impossible to reposition the tile.
