- ‘Following welding the weldment should be annealed and then heat treated to the desired strength level.’
- ‘The most common heat treatments of gray iron are annealing and stress relieving.’
- ‘The white irons of suitable composition can be annealed to give malleable cast iron.’
- ‘Welding of cold-worked alloys anneals the heat-affected zone and eliminates the strength produced by cold working.’
- ‘In heat treatable alloys, annealing also may be accompanied by precipitation and changes in solute concentration.’
- ‘After being annealed, the work metal is quenched in water to free it from particles of the salt mixture.’
- ‘The template and primer were annealed by briefly heating at 80°C and cooling to room temperature.’
- ‘For the high-silicon nodular irons, high-temperature heat treatment is advised in all cases to anneal any pearlite and stabilize the casting against growth in service.’

- ‘The weldment must be stress relived or annealed after welding.’
- ‘He says bright annealed stainless steel is generally specified for medical applications.’
- ‘Unlike annealed stampings, fully hardened electroforms need no heat treating - a process that can distort finished shapes.’
- ‘The heat of welding will anneal the copper in the heat-affected area adjacent to the weld and reduce the strength provided by cold working.’
- ‘Mattinson's idea was to first heat or anneal the zircons, sealing off the least damaged areas of the crystal, then using a strong reagent, hydrofluoric acid, to eat away the heavily damaged areas.’
- ‘The modern range of machinery includes five-axis HSC centres and stretch forming machines, annealing furnaces and chemical milling plants.’

Recombine (DNA) in the double-stranded form.
- ‘The oligonucleotides were annealed by heating the solution of self-complementary oligonucleotides to 94°C using a heat block, and then cooling it to 30°C over the course of 2 h. Annealed DNA was stored at - 80°C until use.’

- ‘These primers were annealed to total RNA from annular cartilage and kidney and extended in the 5’ direction with reverse transcriptase.’
- ‘The one strand of RNA is annealed with its complementary strand of DNA, which causes the other strand of DNA to be displaced from the helix.’
- ‘Two single-stranded oligos, GAGAEXHO and GAGAESAL, were annealed to generate a double-stranded oligo with XhoI and SalI cohesive ends.’
- ‘A mutagenic oligo containing one of the mutations was annealed to a genome carrying the second mutation, and the oligo was extended using T4 DNA polymerase, essentially as in Sambrook, Fritsch, and Maniatis.’

Old English onǣlan, from on + ǣlan ‘burn, bake’ from āl ‘fire, burning’. The original sense was ‘set on fire’, hence (in late Middle English) ‘subject to fire, alter by heating’.
