Hot-dip galvanized steel sheet, member produced using hot-dip galvanized steel sheet, automotive framework structural component or automotive reinforcing component comprising member, and production methods for hot-dip galvanized steel sheet and member

A hot-dip galvanized steel sheet comprising:

• a base steel sheet;
• and
• a hot-dip galvanized layer formed on a surface of the base steel sheet,
• wherein the base steel sheet includes:
• a chemical composition containing, in mass %,
• C:
• 0.030% or more and 0.500% or less,
• Si:
• 0.01% or more and 2.50% or less,
• Mn:
• 0.10% or more and 5.00% or less,
• P:
• 0.100% or less,
• S:
• 0.0200% or less,
• Al:
• 1.000% or less,
• N:
• 0.0100% or less, and
• O:
• 0.0100% or less
• with a balance consisting of Fe and inevitable impurities;
• and
• a steel microstructure at a position of ¼ of a sheet thickness of the base steel sheet in which an area ratio of martensite is 10% or more and 80% or less, an area ratio of ferrite is 20% or more and 90% or less, an area ratio of retained austenite is 10% or less, and a proportion of an area ratio of ferrite having {001} orientation to an area ratio of all ferrite is 0.50 or less, and
• a low-temperature-range diffusible hydrogen content in the base steel sheet is 0.015 mass ppm or less, the low-temperature-range diffusible hydrogen content being an amount of hydrogen released when the base steel sheet is heated up to 50° C.
