Example is Ti it goes from hcp to bcc as the temperature is increased.

I'm looking for around six elements and also I'm having trouble finding the changes, and at what temp they occur. As for Ti at ambient temp it is hcp and when heated to about 890 degrees C it changes to bcc until heated to melting point.

Many elements (not just metals) undergo solid-state, thermally induced phase transitions before melting or sublimating. Sulfur is a classic example, as is tin. Plutonium has a particularly complex phase diagram, with 5 (or 6) different stable allotropes as the temperature increases at room pressure.
See the source below for a link to the full text of the book "Phase diagams of the elements", by David Young. All known phase transitions for the elements are cataloged, and you can pick and choose examples to your heart's content.

Iron goes from bcc to fcc at 910° C .

iron, carbon--just about anything with a crystalline structure
